ALBERT A. KNISELEY, OF DETROIT, MICHIGAN.

GAS HEATER.

Application filed April 17, 1924. Serial No. 707,134.

To all whom it may concern:

Be it known that I, ALBERT A. Kivrsnnnv,

a citizen of the United States. and residing at Detroit, in the countyof l/Vayne and State of Michigan, have invented a new and Improved GasHeater, of which the following is a specification.

This invention relates to gas heaters especially adapted to be used forheating garage structures and it consists in the'novel featureshereinafter described and claimed.

An object of the invention is to provide, a heater which uses gas as afuel with means for leading a current of air from the exterior to theinterior of agarage structure, the parts and features being so arrangedthat the said current of air may absorb the heat units as it passesthrough the heater and consequently is discharged into the garagestructure in a-heated condition.

7 With the above objects in view the heater comprises a housing whichpasses through the wall of the garage structure, a door being hingedlymounted in the housing at its 25 upper edge and at a point between theends of the housing. A gas burner is located in the inner portionof'thehousing and an air conduit is located above the burner and is,

adapted to receive a current of air under the lower edge of the door andfrom the outer portion of the housing and deliver the same through thetop of the housing into the garage structure.

These objects and the several novel features of the invention arehereinaftermore fully described and claimed and the preferred form ofconstruction by whichthese objects are attained is shown in theaccompanying drawings in which Fig. l is a fragmentary section view 0 agarage wall with the heater applied and shown in section.

F'g. 2 is a plan view of the heater.

Fig. 3 is an end elevation of the heater.

Fig. 4 is a fragmentary sectional view of the roof of the garage showinga fume pipe passing therethrough.

As illustrated in the accompanying drawings the wall of agaragestructure is indicated at 1 and the roofthereof at 2. A housingfi'pas'ses transversely through the burner 6 may be maintained in alighted condition all of the time and may light the gas at the burner 4when the valve in the pipe 5 is opened and permits the gas to flow tothe burner 4 in the usual manner. A

fume pipe 7 connects with a cone shaped hood 16 hereinafter referred to.The said pipe 7 passes through the roof 2 as best shown in Fig. 4 of thedrawings. A ventilating sleeve 8 is mo'unted upon the upper portion ofthe pipe 7 and also passes through the roof 2. A flashing 9 is connectedwith the ventilating sleeve 8 and the roof 2 in the usual manner and asshown in Fig. 4 of the drawings.

A door 10 is hingedly mounted at its upper edge in the upperintermediate portion of the housing 3 and is disposed transverselythereof. The door 10 is flanged outwardly atthe lower edge at 12 asshown and a partition 11 is provided across the housing 3 having raisedbeads 30 and 31 which space the door 10 from the panel 11, the doorresting on these beads 30 and 31 and providing an air space between thedoor 10 andpanel 11 to prevent the door from becoming heated. The panel11 is provided atthe lower edge with an inwardly disposed flange 13 anda handle 14 is secured to the lower portion of the door 10.

An air conduit 1518 located in the inner portion of the housing 3 and isdisposed vertically above the burners 4 and 6. The inlet end of theconduit 15 is disposed below the lower edges of the flanges 12 and13-01? the door 10 and panel 11 and the delivery end of the conduit 15passes through the side of a cone shaped hood 16 mounted upon the top ofthe housing 3 and which is located vertically above the said burners.The pipe 7 is connected with the hood 16 as best shown in Fig. 1 of thedrawings. A screen 17 (see Fig. 2) is disposed across the outlet end ofthe conduit and prevents rags or other material from being thrown ordeposited in the conduit. The cone shaped plate 16 prevents the settingof oil cans or similar receptacles upon the top of the housing 3 abovethe burners a and 6. The flange 13 ot the innerpanel 11. is recessed at18 to receive the lower portion oi the conduit 15 as shown in Figl'fllof the drawings. The conduit 15, as will be understood from Fig. 1', isniade up of a series of pipe sections 19, 19", 19, 19 and chambers 20.The lowern'iost conduit 19' is in the form or an elbow having an inletend 19 and opening at its upper end to the lower chamber 20. The nextpipe section 19" connects with the first chamber and discharges to thesecond chamber. The third section l9 connects at one end with the secondchamber and the other end with the third chamber and the last pipesection 19 discharges through the hood 16 and is' provided with ascreened outlet opening 17 as heretofore stated. The pipe sections arear ranged in staggered relation as sl'iown'-that is, the end of one pipesection connects with one side of the chamber and the next pipe sectionconnects with the opposite side of the same. Preferably the chambers aresuccessivelv of less volunietric content successively decreasing indiameter. Baflie' plates 21 are mounted upen the inner surface of theinner panel 11 and are adapted to bear against the edges of the chamberswhere by the fumes and heated gases from the burners 4 and 6 aredirected away from the door 10 and toward the intermediate portions ofthe disks 20. I

It is apparent that when the burners 4 and are lighted the heated gasesandftumes 1 come in contact with the exterior surfaces of the pipes 19and chambers 20' and the heat units are absorbed by the said pipes andchambers and transmitted to the current of air which is passingtherethrou'gh.

The various parts of the conduit 15 are refer-ably welded tegether toprevent a leakage of the gases into the conduit.

From the. foregoing description it be comes evident that the device isvery sir'nple' and efiicient in operation, will not easily get outerorder, provides a safe means for heating a or siniilai? s iuc ture and1'3 1 vit.les a device which accein )lisl1es the objects described.

Having thus-fully described intention, its'utility and mode ofoperation, what l claim and desire to secure by Letters Patent of theUnited States is" V 1:.
